Abstract

The invention discloses an underwater emergency load rejection device. The underwater emergency load rejection device comprises a submersible, a rack is installed at the bottom of the middle standingface of the submersible, a releasing mechanism is installed in the middle of the rack, a heavy block box is installed at the rear portion of the rack, a driving assembly is installed at the front portion of the rack, and the heavy block box is released through the releasing mechanism under the power of the driving assembly. The underwater emergency load rejection device is compact and reasonable in structure and convenient to operate, the load rejection device is installed in a flat space, the emergency capacity is high, safety and reliability are achieved, operation is easy, remote load rejection and rapid floating of the submersible can be manually and rapidly achieved when a power source is lost in an emergency, and the safety of personnel and the submersible is guaranteed.

Description

technical field [0001] The invention relates to the technical field of emergency dumping devices, in particular to an underwater emergency dumping device. Background technique [0002] Manned submersibles are usually equipped with emergency throwing devices and weights. This device is specially designed to deal with emergencies or emergencies when the submersible is navigating underwater. It is a heavy object release device with high reliability and low energy consumption designed to float to the surface of the water at the fastest speed, to ensure the safety of the operators and passengers and the safety of the equipment of the main body of the submersible, so that they can get out of dangerous situations as soon as possible. [0003] The emergency dumping device in the prior art usually adopts methods such as hydraulic oil cylinder jacking up the hook, electric explosion bolt breaking the suspension rod, etc. to discard the heavy block. However, electric explosion bolts a...
